How old are the pictures in your profile? Because I don't see an amateur bodybuilder, and you need to be that before you cross over into competitive bodybuilding. I'm not trying to be mean, just want you to realize the road ahead.
Being a amateur bodybuilder alone takes effort, money, dedication, eating right, and time (both long-term time and daily time). Crossing over into competitive bodybuilding: multiply all this by 10, and there's no guarantee you'll win competitions.
I look at your pictures now, and it looks like you're starting from waaaay at the beginning. I see no trap development. Your lower pecs are hard to gauge underneath the bodyfat, but I can definitely tell there's no upper/inner pec development. You have a little bit of a bicep going on, but (and admittedly, it's a little hard to tell from a bicep-flex pose) your triceps are not developed, and neither are your quadriceps. You're a clean slate, literally.
At this early point in your path, I would start learning the basics. All the basics of lifting and fitness. You can hire a trainer, and it doesn't have to be a bodybuilder (but it has to be a good trainer, because there's a lot of bad ones out there). Or start training with your buddy from work. Or DIY, and start doing programs you got from Men's Fitness magazine or the fitness section of askmen.com (not bodybuilding publications, but great places to start, to learn basic lifts).
Start basic, learn the basics. As you progress more, and as you learn more, you'll be able to understand more advanced lifting advice.
